<p>到这部如果没有报错的话，运行 aplay -l、lspci | grep -i audio应该都可以看到NVIDIA的相关信息了。在设置页面中中也可以看到以HDMI为声音输出的选项了。</p>
<h3 id="3：设置开机服务器"><a href="#3：设置开机服务器" class="headerlink" title="3：设置开机服务器"></a>3：设置开机服务器</h3><p>经过2 显示器的内置音响应该可以用了，但是需要每次开启都手动去启动服务器，非常的麻烦，所以3是如何开机后自动去启动服务器，并开启HDMI声音输出</p>
<blockquote>
<p>1）:自动加载模块</p>
<p>将模块名称<strong>nvhda</strong>贴入 <strong>/etc/modules</strong> 文件即可。</p>
<p>命令</p>
</blockquote>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">sudo gedit &#x2F;etc&#x2F;modules</span><br></pre></td></tr></table></figure>

<p>在文件中输入 <strong>nvhda</strong> 并保存</p>
<blockquote>
<p>2）:自动开启声卡</p>
<p>在第2下载的 <strong>nvhda</strong> 的项目内，作者已经封装好了服务和脚本供我们使用，所以一定要在 <strong>nvhda</strong> 项目内输入以下命令</p>
</blockquote>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">sudo cp scripts&#x2F;nvhda-start.service &#x2F;etc&#x2F;systemd&#x2F;system</span><br><span class="line">sudo systemctl enable nvhda-start</span><br><span class="line">sudo cp scripts&#x2F;nvhda-resume.service &#x2F;etc&#x2F;systemd&#x2F;system</span><br><span class="line">sudo systemctl enable nvhda-resume</span><br></pre></td></tr></table></figure>
